Declaration:property ValueSec: double;

The ValueSec property specifies the value dislayed by the secondary needle. Setting the ValueSec property to a new value automatically moves the index of the secondary needle into the appropriate position. In addition, the over- or underflow indicators are set accordingly (if turned on), and the events OnNormalRange, OnOverFlow, OnUnderFlow are triggered according to the value.

Hint: The secondary needle is invisible by default. Thus you have to set the sub-property Visible of the property NeedleLayoutSec to TRUE in order to make the secondary needle visible.

Example: This property is used in the following example program (see for downloading the code): prjmeter
